The Real Housewives of Atlanta star had a fire emergency Wednesday morning when the garage of her Roswell, Georgia home went up in flames. Fortunately, the fire department acted quickly and extinguished the blaze with no significant damage or injuries; other areas of Zolciak's sprawling home were unaffected.

A rep for the Roswell Fire Department confirmed to TMZ they sent fire trucks to Zolciak's house after receiving a call about a garage fire. The near-catastrophe began when an ATV in the Bravo star's garage caught fire.

Zolciak, 34, is currently expecting her second child (a boy!) with husband Kroy Biermann, whom she married last November. The couple welcomed their first child, Kroy, Jr., together on May 20, 2011 and announced their second pregnancy just 10 months later. The reality star also has two daughters -- Brielle, 15, and Ariana, 9 -- from previous relationships.
